KatujahtiFrom street to Side PathAnimated gameplay example
Katujahti 2.1 opens the map: streets are now playable in 41 European countries besides Finland, and the new Tailwind challenge adds an optional game within your walk.
ALL OF EUROPE
Play across Europe.
Streets are playable in 41 European countries, from Iceland to Cyprus. Municipality search works across Europe without a network connection, and the map goes from municipality to country, Europe and the whole world.
The app is downloaded from the Finnish App Store and Google Play, and the game works abroad too.
Tailwind, a challenge within your walk.
An optional walking challenge: walk a stage within the given time, keep your streak going and raise your multiplier. New streets earn a bonus, and a route suggestion appears on the map.
Shared World covers every country.
The community map now shows in which countries and municipalities people have walked. Taking part is optional, as always.
New statistics and share images.
Statistics by period, history as a list, calendar or map, and drill-downs from a municipality to its areas and streets. Share images come in two sizes, and the app now speaks German and French too.
More accurate and more stable.
Gaps at junctions are filled, a footpath next to a big road is recognised, and more GPS points are accepted. Long walks, switching municipality and restoring an interrupted walk are more reliable.

THE KATUJAHTI STORY
From a family game to streets across Finland.
Katujahti started with Johanna’s idea and the family’s walks. With help from testers, it grew into a game for all of Finland.
- The first streetsJuly 2026
What if we walked them all?
Johanna read in Helsingin Sanomat that Pentti Arajärvi had walked every street in Helsinki. She discussed the idea with her husband Jussi, and it became a walking game for the family. Katujahti marked the streets they had walked on a map, making it easy to choose new ones for the next walk.
- All of Finland28 July 2026
From home streets to 308 municipalities.
The game grew to cover Finland. Over 224,000 streets, local areas and three languages. Downloaded streets could be collected offline too.
- Built with testersAugust 2026
Into the pocket and out for a walk.
The iPhone and Android apps went on real walks. Testers helped improve street detection, background recording and the map before the store release.
